ORAL B Glide Pro-Health Floss
Lower concern, but ePTFE material warrants caution; no public PFAS testing available.
Oral-B Glide Pro-Health uses expanded Teflon-type coating (ePTFE), a Teflon-family coating material. While ePTFE dental floss has not been flagged in major recalls or public health warnings, Teflon-type coating-based products can contain PFAS residues depending on manufacturing. Oral-B makes no public PFAS disclosure for this product.

The full breakdown
What it's made of and why it matters
Oral-B Glide Pro-Health uses expanded polytetrafluoroethylene (ePTFE), a porous version of Teflon-type coating that shreds less than traditional floss and slides easily between teeth. ePTFE is chemically stable and inert in the mouth; the small amounts that might be ingested during flossing are not absorbed by the gastrointestinal tract and pass through the body unchanged. The material is FDA-cleared for oral contact, and the floss itself is not heated during normal use, which eliminates the main pathway for Teflon-type coating fume release (fumes occur only above 500°C). For dental floss specifically, the exposure window is measured in seconds per day, making material hazard concentration very low.
The brand's record and disclosure
Oral-B (owned by Procter & Gamble) does not publicly disclose whether their ePTFE floss contains intentional PFAS additives or whether residual PFAS from manufacturing are present. The brand has not pursued third-party testing or PFAS-free certification for this product line. P&G has committed to phasing down certain PFAS in other product categories but has not extended public commitments to dental floss. No recalls or safety warnings specific to Oral-B Glide floss are on record with the FDA or other regulatory bodies.
How it compares in its category
Most commercial floss products (including nylon, Teflon-coated, and natural alternatives) carry similar or higher uncertainty regarding PFAS content, as the floss industry is largely unregulated for these chemicals. Oral-B Glide is among the most widely used brands globally and has the advantage of long-term safety surveillance through routine use; any acute hazard would likely have surfaced in adverse-event reports by now. Natural alternatives (silk, bamboo) avoid synthetic polymers entirely but may have lower efficacy or lack FDA clearance for floss claims.
If you buy it
Use as directed: floss once daily, do not swallow deliberately, and dispose of used floss in the trash (not toilets, as it does not break down). Do not heat or burn the floss. Replace the spool or cartridge when floss becomes difficult to dispense or frayed. If you have concerns about PFAS exposure, consider rotating with natural-fiber alternatives on alternate days, though there is no evidence that this reduces risk meaningfully. Keep the product away from children under 3 who cannot spit reliably.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Teflon-type coating/Teflon-family coating fume inhalation
Fumes only release above 500°C; floss is not heated during normal oral use. No fume incidents reported for dental floss products.
Microplastic or fiber shedding
ePTFE is designed to minimize shredding compared to traditional nylon floss, but microscopic fibers may be released during vigorous flossing. Swallowed fibers pass through the GI tract without absorption; risk is theoretical and not established to cause harm in normal use.
Unintentional ingestion of floss material
ePTFE is inert and not absorbed; small amounts ingested incidentally during flossing are excreted unchanged. No toxicity has been established for oral-contact-approved Teflon-family coating in trace amounts.
Residual manufacturing contaminants or solvents
Oral-B products are manufactured under FDA oversight and cosmetic/dental device standards, but no public testing for residual solvents (e.g., N-methylpyrrolidone) specific to this floss is available.
Allergic reaction or oral irritation
ePTFE is hypoallergenic and non-irritating in clinical use. No adverse-event pattern has been reported for Oral-B Glide in regulatory databases.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 55% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
